MATTRESS-SOTITCIHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 621,650, dated March21, 1899. Application filed September 19, 1898. Serial No. 691,313. (Nomodel.) 7

T aZZ whom it may concern;

Be it known that I, ELIJAH T. GASKILL, a citizen of the United States,residing at New Berne, in the county of Craven and State of NorthCarolina, have invented a new and useful Improvement inMattress-Stitching Machines, of which the following is a specifica tion.

My invention is an improvement in apparatus for stitching mattresses;and it consists in certain novel constructions and combinations ofparts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a transverse section of my apparatus as inuse. Fig. 2 is a front elevation thereof. Fig. 3 is a sectional view onabout line 3 3 of Fig. 1, and Fig. 4 is a detail perspective viewof thead'- justable clamp. I

In carrying out my invention I employ a suitable frame A, which isprovided with ways B for the carriage O, which supports thesewing-machine D. The frame also has in the construction shown anelevated stand E, carrying the inclined platform F, on which issupported the mattress to be stitched, such which may be clamped by thelevers h to compress them upon the portions of the mattress to be sewed,as will be understood from Fig. 2, such portion of the mattressextending over the bed D of the sewing-machine in position to bestitched by such machine as the latter moves along the seam. Theseclamps hold the mattress stretched tightly in proper position to bestitched and prevent any rucking of the material.

The sewing-machine D is designed for operation by hand and has its mainshaft D arranged to operate the shaft I of the feeding devices, whichoperationmay be effected by the connecting-bar J, as shown in Fig. 1. Asthe shaft I is revolved, or oscillated, if preferred, it operates togive the carriage O a step-by-step movement along the mattress.

In the construction shown I provide the framing with a ratchet-bar K andthe shaft I with an eccentric L, operating in an eccentric-' strap M ona pawl M, which latter engages the teeth of the bar K and feeds thecarriage along the frame when the shaft I is operated as beforedescribed. The downward movement of the pawl M is limited by thestopbail N, the pawl being pressed downward by a spring 0 and arrangedto be lifted clear of the bar K by means of the rod P and itsoperating-lever P when the latter is adjusted, as shown in Fig. 3. Thisis desirablewhenever the operator wishes to use the apparatus withoutthe automatic feed. r

In the operation of my invention, the parts being as shown in Figs. 1and 2 and the seam to be stitched being secured by and between theclamps H and 1-1, the operator may turn the shaft D to operate thesewing devices and at the same time operate the feeding de vices, asbefore described.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The herein described apparatus for stitching mattresses consisting ofthe frame, the carriage supporting the sewing-machine and provided witha shaft having an eccentric the pawl having a strap fitting on saideccentric, a spring for pressing the pawl into engagement with afeed-bar on the framing,

and a lever and connecting-rod for lifting said pawl clear of saidfeedbar, substantially as set forth.

2. In an apparatus substantially as described, the combination of theframe, the sewing-machine and its carriage, the shaft journaled to suchcarriage and having a crank, driving connections between said crank andthe sewing-machine, the eccentric on said crank-shaft,the pawl having aneccentric-strap encircling the eccentric, the

feed-bar arranged for engagement by the pawl, the spring for forcing thepawl into such engagement, the bail for limiting the movement of thepawl, and means for operating the pawl against the action of its springsubstantially as set forth. 4
